'Wine-and-cheese crowd' to open Levi's Stadium

1 / 37

Back to Gallery

Want to see how far the 49ers crowd has come from bratwurst in the Candlestick parking lot and beer in the bleachers at Kezar? Check out the black-tie gathering that will open Levi's Stadium in Santa Clara.

There's a very VIP gala at the stadium Saturday, two days after politicians, civic leaders and the like cut the ribbon on the $1.2 billion stadium. A wine-tasting party for suite holders follows later in the month.

"They've always said it was a wine-and-cheese crowd. I guess the image is just playing out," said Santa Clara County Assessor Larry Stone, who is getting his tux pressed for Saturday's party.

The upscale tone of the stadium's opening will continue throughout the season - and then some.

Celebrity chef Michael Minawill have a year-round restaurant at the stadium with a parking lot that will turn into a tailgate section on game days.

Concessions stands will sell 16 types of wine and an assortment of cheeses. In all, fans will have 180 menu items to choose from.

What's more, "we'll have more vegan options than any other stadium, and none of them are tofu," said Diana Evans, marketing director for Centerplate concessions, which has the chow contract for the stadium.

For those who just want a hot dog and beer, there will be hormone- and nitrate-free franks in natural casings steamed over an organic tomato and mustard seed broth. They'll be served on Le Boulanger buns that are custom baked, so that the final product won't overwhelm the meat and condiments with dough.

The price of that dog: to be announced on opening day.

Nadia tales: Intrigue swirls around state Treasurer Bill Lockyer's wife and former Alameda County Supervisor Nadia Lockyer and that back injury she reportedly suffered in a fall at the couple's Hayward home.

On her Facebook page, she posted that she had fractured her vertebra when she tripped "on a narrow spiral staircase going from our balcony to grass below."

Hayward Police Lt. Bobbie Kollerwould tell us only that the call came from an undisclosed male member of the household at about 8:30 p.m. on July 5.

"There was concern about her state of mind," Koller said. She declined to say more, citing federal law protecting patients' privacy.

Nadia Lockyer resigned as a supervisor in 2012 after a drug and sex scandal and has since been treated for substance abuse. Koller wouldn't say whether she appeared to be impaired when officers arrived.

She said on her Facebook page that she had broken her back. Interestingly, two days later she was sending out messages from her bed at a second Kaiser hospital 400 miles to the south in Orange County - where, as best we can tell, her husband had driven her after her quick release up north.

Out of the loop: Lots of handwringing at BART headquarters over the shortage of trains for the recent Pride Parade celebration in San Francisco that left passengers stranded at stations for 40 minutes or longer.

After the June 29 parade - BART's second-busiest Sunday on record - Saltzman says she was deluged with texts, e-mails and phone calls from unhappy constituents in her district, which sprawls from Lafayette to El Cerrito. Some complained about being stuck on the platform as packed trains passed by, and others said they had been forced to abandon their parade plans altogether.
